# Desert Bloom Energy Storage, LLC; Notice of Preliminary Permit Application Accepted for Filing and Soliciting Comments, Motions To Intervene, and Competing Applications
On March 11, 2025, Desert Bloom Energy Storage, LLC filed an application for a preliminary permit, pursuant to section 4(f) of the Federal Power Act (FPA), proposing to study the feasibility of the Desert Bloom Energy Storage Project (Desert Bloom Project or project) to be located near the city of Las Vegas in Clark County, Nevada. The proposed project would occupy federal land managed by the Bureau of Land Management. The sole purpose of a preliminary permit, if issued, is to grant the permit holder priority to file a license application during the permit term. A preliminary permit does not authorize the permit holder to perform any land-disturbing activities or otherwise enter upon lands or waters owned by others without the owners' express permission.
The proposed project would consist of the following new facilities: (1) an upper reservoir with a storage capacity of 4,900 acre-feet; (2) a lower reservoir with a storage capacity of 4,900 acre-feet; (3) an approximately 4,300-foot-long, 21-foot-diameter steel and concrete penstock; (4) a 200-foot-long, 100-foot-wide, 150-foot-high underground powerhouse with two reversible 225-megawatt Francis-type pump/turbines; (5) an approximately 3.5-mile-long, 132-kilovolt transmission line that would interconnect the project with the grid at an existing substation operated by the Nevada Power Company; and (6) appurtenant facilities. The proposed project would have an estimated annual generation of 1,170,000 megawatt hours operating five days a week.
